Update: The big wildfire in northwest Wisconsin is contained. However, it has scorched 9,000 acres and destroyed dozens of homes and buildings.
Because of dry, warm, windy conditions in much of the state, the DNR is suspending all burning permits and warning people not to start fires. According to the agency, the danger of large forest fires is "Very High" in most of Wisconsin.
The DNR and National Weather Service have issued a Red Flag Warning for Florence and Marinette counties, stating that extreme weather conditions there could easily fuel small flames, hot coals, sparks and vehicle exhaust systems.
People are also urged not to smoke in woody or grassy areas and to phone 911 when noticing smoke in the air.
Hazardous conditions are expected to continue until the weather pattern changes.
